Answer

You can still say "Thank you" and look at them all that way they know it's directed towards them. You don't have to thank them individually unless you really want to.

Answer

Yes. You can interchange "i appreciate+all your help /i'm grateful+ for your help". 
you can simply say. Thanks everyone for helping me. =)

Answer

You can say, " I'd like to thank Sara , Nora and Susan for  all their hard work"
